OEX Alternator 12V 60A Denso Style DXA4122

The OEX Alternator DXA4122 is a new 12V, 60A alternator built in a Denso style configuration. It is listed as an alternator with an internal regulator, a single leg alternator mount, and a pulley section A, so it suits buyers comparing fitment details rather than relying on a generic match.

Key physical details include a 69mm pulley outside diameter, 10mm pivot hole diameter, M8x1.25 adjusting hole diameter, 23.5mm mount leg thickness, and 153mm mount centre to centre. Those measurements are the important checkpoints when matching against an existing alternator or vehicle application.

This unit is supplied under the OEX brand and carries part number DXA4122. It is covered by a 3 year passenger / 1 year commercial warranty, which is a useful consideration for buyers needing a replacement rotating electrical component for a compatible application.

Application and Buying Notes

Before ordering, compare the alternator part number DXA4122, the Denso style layout, and the mounting measurements against the unit being replaced. The 10mm pivot hole diameter, M8x1.25 adjusting hole diameter, 23.5mm mount leg thickness, and 153mm mount centre to centre are the main physical checks that help separate similar-looking alternators.

The 60A output and 12V system rating matter when matching the charging system requirement of the machine. This unit also uses an internal regulator, so the regulator arrangement should be confirmed against the original alternator before purchase or installation.

The listed fitment references include John Deere and Kubota applications, but that does not replace a direct check of the existing alternator, mounting style, pulley setup, and part number. If the old unit is available, compare the pulley section A, 69mm pulley outside diameter, and single leg mount as part of the identification process.

For commercial use, the warranty is listed as 1 year, while passenger use is listed as 3 years. That difference is worth noting when the alternator is being selected for a machine used in a mixed or business environment, especially where operating time and service intervals are important.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number DXA4122 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.
